欣諭真空冷凍干燥機(jī)所有需要控制和調(diào)節(jié)的儀器都安裝在兩個(gè)各自D立的柜子中：電氣柜用于電氣系統(tǒng)，控制柜用于儀表和控制系統(tǒng)?？刂乒衽c電氣柜通過(guò)15 米的連接電纜連接（不提供電纜橋架）。額外的電纜需付費(fèi)。PC 機(jī)配有6 米電纜用于RS232 與PLC 的連接，提供更長(zhǎng)的需額外付費(fèi)。如電纜長(zhǎng)度超過(guò)15米，需要將通訊協(xié)議更換到RS422。 控制系統(tǒng)包括一個(gè)記錄儀及打印機(jī)。
All the required control and regulating devices are installed in two separate cabinets: a power cabinet for the electrical system; a control cabinet for the instrumentation & control system. The control cabinet is connected to the power cabinet by 15m of interconnecting cable (cable trays are not provided). The PC is provided with 6m of cable for RS232 connections to the PLC. Optional longer cables can be provided, which makes the communication protocol change to RS422, for cable lengths over 15m. A recorder and printer are provided as standard with the control system.
設(shè)備的各部件都連接到電氣柜的接線端子上。提供接線端子的編號(hào)確認(rèn)。電氣柜包括確保安全操作所必須的元件，如主電源連接及隔離，與現(xiàn)場(chǎng)電源匹配，變送器及控制電源。控制電壓24V DC 用來(lái)Z大程度確保系統(tǒng)安全。
Equipment components are connected to terminals in the power cabinet and ready for use. The terminals are numbered to provide a clear identification. The power cabinet includes all the necessary components to ensure the safe operation of the plant, including main power connections and isolation, to match the local supply, transformers and power supplies for control. Where practical skid control voltages are 24V DC to maimize system safety.
